Sainsbury, the UK retailer is testing a shopping trolley with an inbuilt iPad dock.

iPad shopping trolley launches

The trolleys come complete with a tilting iPad holder and speakers. Their front bumpers are fitted with a sensor which lets off a warning beep if an engrossed shopper gets too close to another customer, while an onboard battery with a self-charging solar panel ensures that the iPads never run out of power.

The trolleys have been developed by broadcaster Sky to highlight its Sky Go service, which allows iPad users to watch live sport or news on their portable devices. The iPads themselves are not included.
